BACKGROUND
Antipsychotic-induced metabolic syndrome (MetS) is a multifactorial disease with a genetic predisposition. Serotonin and its receptors are involved in antipsychotic-drug-induced metabolic disorders. The present study investigated the association of nine polymorphisms in the four 5-hydroxytryptamine receptor () genes , , , and and the gene encoding for the serotonin transporter with MetS in patients with schizophrenia.
METHODS
A set of nine single-nucleotide polymorphisms of genes of the serotonergic system was investigated in a population of 475 patients from several Siberian regions (Russia) with a clinical diagnosis of schizophrenia. Genotyping was performed and the results were analyzed using chi-square tests.
RESULTS
Polymorphic variant rs521018 () was associated with higher body mass index in patients receiving long-term antipsychotic therapy, but not with drug-induced metabolic syndrome. Rs1150226 () was also associated but did not meet Hardy-Weinberg equilibrium.
CONCLUSIONS
Our results indicate that allelic variants of genes may have consequences on metabolic parameters. MetS may have too complex a mechanistic background to be studied without dissecting the syndrome into its individual (causal) components.
背景
抗精神病药物所致代谢综合征（MetS）是一种具有遗传易感性的多因素疾病。血清素及其受体参与抗精神病药物所致的代谢紊乱。本研究调查了4个5-羟色胺受体（5-HT）基因（HTR1A、HTR2A、HTR2C和HTR7）以及血清素转运体（SLC6A4）编码基因中的9个多态性与精神分裂症患者MetS的相关性。
方法
在来自俄罗斯几个西伯利亚地区的475例临床诊断为精神分裂症的患者群体中，研究了一组血清素能系统基因的9个单核苷酸多态性。进行基因分型，并使用卡方检验分析结果。
结果
多态性变体rs521018（HTR2C）与接受长期抗精神病治疗的患者较高的体重指数相关，但与药物所致代谢综合征无关。Rs1150226（HTR2A）也有相关性，但不符合哈迪-温伯格平衡。
结论
我们的结果表明，5-HT基因的等位基因变体可能对代谢参数有影响。MetS的机制背景可能过于复杂，在不将该综合征分解为其各个（因果）组成部分的情况下难以进行研究。
